President George Vella non-committal over embryo testing Genetic testing of IVF embryos may encounter presidential resistance 2 May 2021, 10:00am by Kurt Sansone President George Vella has remained non-committal as to whether he will sign into law a Bill introducing genetic testing of embryos produced by in-vitro fertilisation. “We will cross the bridges when we come to them,” a spokesperson told MaltaToday when asked whether the President had any moral objections to pre-implantation genetic diagnosis (PGD) and whether he will refuse to sign the law. Any act of parliament requires the President’s signature to become law and refusal to do so could create a constitutional crisis.
